This market will resolve based on the data for the Global Land-Ocean Temperature Index for April 2026 versus the data points available for all other Aprils on record. Note: If April 2026 is tied for first, second, or third hottest with another year, it will qualify for the bracket it ties with. The primary resolution source for this market will be the figures found in the table titled "GLOBAL Land-Ocean Temperature Index in 0.01 degrees Celsius" under the column "Apr" (https://data.giss.nasa.gov/gistemp/tabledata_v4/GLB.Ts+dSST.txt). If NASA's "Global Temperature Index" is rendered permanently unavailable, other information from NASA may be used. If no information for April 2026 is provided by NASA by May 31, 2026, 11:59 PM ET, a consensus of credible sources will be used to resolve this market.Preliminary ERA5 reanalysis data for April 1, 2026, shows global surface air temperature (2m) reaching an exceptionally high level for early spring, positioning it perilously close to the current second- and third-hottest days on record—narrowly separated summer peaks from 2024 at around 17.1°C—driving trader-implied odds of 37% for third hottest and 34% for second. This stems from persisting positive anomalies after 2025's third-warmest year ranking (Copernicus), amplified by the La Niña-to-ENSO-neutral transition (NOAA CPC March update), which lifts suppression on global averages. Differentiating factors include final data revisions for April 1 and model consensus for April 2-3 peaks, with inherent reanalysis uncertainty; Copernicus updates expected in 5-6 days could clarify rankings amid ongoing warming trends.
